VPF-to-Pad Operations

Back in the VPF in preparation for transfer, the VPF platforms are moved to the top of the workstand, the pre-configured canister and transporter positioned at the VPHD, and the entire cargo transferred into the canister. Those payload required specific service (instrumentation, monitor, fluids and gases, and electrical power) are connected to the canister supporting subsystems. Subsystems are activated, service verified, unique access gear removed, and the VPHD and workstand planks are retracted. The canister is moved clear of the VPHD and workstand, and the canister doors closed. The canister Environmental Control System is then activated.


The transporter cab is manned for continuous monitoring of instrument functions, services, and canister road status. Using facility power through an extension cable, the transporter/canister is moved through the airlock high bay doorway into the airlock and the high bay door is closed to preserve the high bay clean room status. The airlock external door is opened next and the transporter/canister is moved outside the airlock. (This movement is contingent on compatible weather conditions and the time of day selected is during a low traffic period. ) The facility power extension is disconnected, the airlock door closed, and the integral electrical power system and prime mover power systems activated.

KSC security and fire personnel and contingency-access payload user and payload integration personnel accompany the move. The transporters is driven at a speed not exceeding 5 miles per hour (8.05 km per hour) to launch pad 39A or 39B. The canister remains vertical on the approach up the pad ramp to the RSS by use of the transporter self-leveling system. The canister is precisely positioned under the RSS by moving the transporter to a marked 'park' position.
